Mallard's Restaurant, Nashville

When owner Bobby Nelson opened this Southern-style diner, he had no idea how popular a spot it would become. Finding a table is next to impossible during lunch hours, but for those fortunate enough to score one, culinary nirvana awaits. The restaurant offers five meat entrees and seven vegetables daily, all prepared fresh. The restaurant features pit-smoked barbecue every evening. On Fridays, try the famous all-you-can-eat catfish dinner. And don't miss the best part of any meal here, Banana Split Pie, a decadent blend of banana pudding, ice cream and graham crackers.
